Do not coat over caulking. If caulking is not removed, and is painted up to caulking, coating subject to delamination along caulk edge. 1.) Surface Preparation: Solvent Clean, per SSPC SP-1, the substrate to remove any contamination that may be present, including any silicone residue and chlorides. 2.) Abrade substrate, similar to SSPC-SP-2/3, to remove any loose factory coatings and field applied coatings, sheen, contamination, while creating a minimum surface profile of 1.0 mil. on both any bare metal and coated substrates. 3.) Corroded Surface: Prepare any corrode surfaces similar to per SSPC SP-15, Commercial Grade Power Tool Cleaning, removing existing coatings, rust, oxides, mill scale, while obtaining a surface profile of 1.5 to 2.0 mils. Feather sand edges. Prime the same day to avoid oxidation. Apply one coat of Coraflon ADS 511/512 Primer, using multiple passes spraying, @ 3.0 5.0 mils DFT. May require multiple passes or coats to achieve recommended dft. All edges and bolts to be stripe coated. 4.) Prior to coating, solvent wipe or tack off substrate to remove dust and residual contamination. 5.) Before each coating operation, surface will be clean, dry, contamination free. Primer to be supplied by PPG Industries, Inc. Apply one coat of Coraflon ADS 511/512 Primer, using multiple passes spraying, @ 2.0 3.0 mils DFT. May require multiple passes or coats to achieve recommended dft. All edges and bolts to be stripe coated. Coraflon Intermix-Color Permitting to be supplied by PPG Industries, Inc.
